If it's flowing through the radiator, it will be flowing through the engine.
Radiator flow can be checked by running the engine, with the cap removed, and looking into the opening. Whether the coolant is moving, or not, will be obvious. Judging whether the flow is adequate, is best left to someone with some experience, in that area.
My advice, in
post #67 applies.

No need to go into the engine, unless the diagnosis points in that direction and it has been verified. The chemical test, I mentioned in
post #67 is how it is verified.

OP said he tested his 160° and it worked. However, if it did stay open, it would have the same effect (it would never get up to operating temp) as no thermostat at all.

Another Wives tale/Internet Myth.

If both hoses are the same temp, there is a flow (air or liquid) problem. If the lower hose is substantially cooler, there is no problem.
